Ethereal Merchant

History
Ethereals live on their homeplanet of K'aresh, yet a few of them traverse the Twisting Nether to visit locations of importance and strong Void-influence, be they worlds consumed by Nether or merely the locations of powerful Ley-Lines.

''The Ethereal Merchants make their living searching or trading for valuable artifacts, known as "Space Traders" to some. They are capable of creating Void-portals to travel, but are very hesitant to share their magics with outsiders... Without a price.''

Trivia:

 * The adventurers spotted a group of Ethereal Traders in the Ancient Library, stealing whatever ancient books the zealous Voidblades did not deem "forbidden knowledge".
 * The party did not get to interact with the merchants. As soon as the Voidblades fell in battle, the merchants escaped through their Void-Portals.
